Waste management

Gazprom Neft’s industrial waste management system aims to ensure environmentally sound waste management, optimise waste flows, mitigate the environmental impact and reduce the economic cost of waste generation. The Company strives to maximise the possible use of waste in order to mitigate its environmental impact.

In 2016, Gazprom Neft developed a concept for the utilisation of drilling waste in order to mitigate environmental risks and reduce well construction costs. The concept takes into account the infrastructure of the fields under development, the existing technologies for and disposal drilling waste, key performance indicators, well construction methods (sump and sump-less drilling), waste injection into the reservoir and remote fields. The concept is to be introduced at the subsidiaries of the Upstream Division in 2017.

During the reporting year, the Company began introducing sludge pit reclamation technology using environmentally friendly soil obtained from drill cuttings. In 2015, the technology underwent testing at a number of the Company’s fields and was given a favourable conclusion as part of a state expert environmental review. Gazpromneft-Noyabrskneftegaz successfully used the method to reclaim sludge pits.

Moscow Oil Refinery modernisation programme

The Moscow Oil Refinery has obtained a waste management license. Starting in 2016, all enterprises that collect, transport, process and recycle waste are required to have a license in accordance with federal legislation. The refinery has been implementing a large-scale modernisation programme since 2011 as part of which all waste that accumulated prior to 1991 has been eliminated. Over the five years of the programme, the enterprise recycled more than 180,000 tonnes of oily waste, freed up roughly 15 hectares of the refinery’s territory and reclaimed polluted soil.
